Standard ICs BU2090 / BU2090F / BU2090FS / BU2092 / BU2092F / BU2092FV 12-bit, serial IN, parallel OUT driver BU2090 / BU2090F / BU2090FS / BU2092 / BU2092F / BU2092FV The BU2090, BU2090F, BU2090FS, BU2092, BU2092F, and BU2092FV are 12-bit serial input, parallel output drivers. For the BU2090 / F / FS, data input is shifted to the 12-bit internal shift register on the rising edge of a clock pulse. On the falling edge of the pulse, if the DATA pin is HIGH, the data in the shift register is outp.

Standard ICs BU2090 / BU2090F / BU2090FS / BU2092 / BU2092F / BU2092FV 12-bit, serial IN, parallel OUT driver BU2090 / BU2090F / BU2090FS / BU2092 / BU2092F / BU2092FV The BU2090, BU2090F, BU2090FS, BU2092, BU2092F, and BU2092FV are 12-bit serial input, parallel output drivers. For the BU2090 / F / FS, data input is shifted to the 12-bit internal shift register on the rising edge of a clock pulse. On the falling edge of the pulse, if the DATA pin is HIGH, the data in the shift register is output in parallel to Q0 to Q11. For the BU2092 / F / FV, shift data read at the rising edge of CLOCK is output in parallel to Q0 to Q11 at the rising edge of LCK. These ICs also have an OE pin, which when HIGH, forces data to be output, regardless of the shift data state. Applications • Radio cassette players, telephones, compact audio systems, car stereos, and others Features • 1) Low power dissipation. 2) Operating voltages ranging from 2.7 to 5.5V. 3) Output is Nch open drain. 4) High output withstand voltage of + 25V. 5) Diverse variety of packages. BU2090 / F / FS: DIP16, SOP16, SSOP-A16 BU2092 / F / FV: DIP18, SOP18, SSOP-A18 (plastic molds) 6) High drive capability; direct lighting of green LED possible. 1 Standard ICs maximum ratings (Ta = 25°C) •Absolute (BU2090 / F / FS, BU2092 / F / FV) Parameter Power supply voltage Power dissipation Power dissipation BU2090 / F / FS BU2092 / F / FV BU2090 / F / FS BU2092 / F / FV Symbol VDD Pd Limits – 0.3 ~ + 7.0 BU2090 / BU2090F / BU2090FS / BU2092 / BU2092F / BU2092FV Unit V mW 1000 (DIP), 300 (SOP), 500 (SSOP)∗1 1050 (DIP), 450 (SOP), 400 (SSOP)∗1 500 (SOP)∗2, 650 (SSOP)∗3 500 (SOP)∗2, 650 (SSOP)∗4 – 25 ~ + 75 – 55 ~ + 125 VSS – 0.3 ~ VDD + 0.3 VSS ~ 25.0 Pd Topr Tstg VIN VO mW °C °C V V Operating temperature Storage temperature Input voltage Output voltage ∗1 Unmounted ∗2 When mounted on a glass epoxy board of 50mm × 50mm × 1.6mm ∗3 When mounted on a glass epoxy board of 90mm × 50mm × 1.6mm ∗4 When mounted on a glass epoxy board of 70mm × 70mm × 1.6mm •Recommended operating conditions Parameter Power supply voltage Symbol VDD Limits 2.7 ~ 5.5 Unit V 2 Standard ICs BU2090 / BU2090F / BU2090FS / BU2092 / BU2092F / BU2092FV •Block diagram BU2090 / F / FS BU2092 / F VSS 1 VSS 1 DATA 2 CLOCK 3 Q0 4 Output buffer (open drain) Control circuit 18 VDD 17 OE Control circuit 12-bit shift register Latch 16 VDD 15 Q11 DATA 2 12-bit shift register CLOCK 3 14 Q10 16 Q11 112-bit storage register LCK 4 13 Q9 15 Q10 14 Q9 13 Q8 12 Q7 11 Q6 10 Q5 Q0 5 12 Q8 Q1 5 Q2 6 Q3 7 Q4 8 Output buffer (open drain) Q1 6 11 Q7 Q2 7 10 Q6 Q3 8 9 Q5 Q4 9 BU2092FV VSS 1 DATA 2 12-bit shift register Control circuit 20 VDD 19 OE 18 Q11 CLOCK 3 LCK 4 Q0 5 Q1 6 Q2 7 Q3 8 Q4 9 Q5 10 12-bit storage register 17 Q10 16 Q9 15 Q8 14 Q7 13 N.C. 12 N.C. 11 Q6 Output buffer (open drain) 3 Standard ICs BU2090 / BU2090F / BU2090FS / BU2092 / BU2092F / BU2092FV •Pin descriptions Pin No. BU2090 / F / FS 1 2 3 — 4 5 6 7 8 9 10 — — 11 12 13 14 15 — 16 BU2092 / F BU2092 / FV 1 2 3 4 5 6 7 8 9 10 11 — — 12 13 14 15 16 17 18 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 Pin name VSS DATA CLOCK LCK Q0 Q1 Q2 Q3 Q4 Q5 Q6 N.C.
